GEORGE M. WILLIAMS, OF SANTA ROSA, CALIFORNIA.

TRUCK.

SPECIFICATION forming part of Letters Patent No. 653,431, dated July 10, 1900.

Application filed January 19. 1900. Serial No. 2,023. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M. WILLIAMS, a citizen of the United States, residing at Santa Rosa, in the county of Sonoma and State of Oalifornia,have invented certain new and useful Improvements in Truck-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improve ments in trucks, pertaining to that class especially adapted for use in stores, warehouses, and like business places for readily moving or transporting barrels, boxes, ($50.

It has for its objects principally to provide for the ready and convenient locking and unlocking of the truck-wheels as relates to their turning or non-rotation upon their axle as occasion may require, to effect the manipulation or application and disengagement of the lock, and to otherwise provide for efficiency and facility in the use of the device.

It consists of the combination, construction, and arrangement of certain parts for carrying out the foregoing objects, substantially as hereinafter more fully disclosed, and specifically pointed out in the claims.

It will be understood that latitude is allowed herein as to details, as they may be changed or varied according to circumstances without departing from the spirit of my invention and the same yet remain intact and be protected.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a longitudinal section. Fig. 2 is a broken sectional view. Fig. 3 is a rear underneath View. Figs. 4 and 5 are views of a modification of the invention.

In carrying out my invention I employ a truck 1 of the character above described, in its general construction such as ordinarily used, and in connection therewith'use a brake or look for the relative locking and unlocking of the wheels 2. This lockcomprisesatransverse sliding or movable bar 3, adapted to engage said wheels especially designed therefor, as

presently seen, and arranged or supported in position in slotted or skeleton castings or brackets 4, adapted to be conveniently secured to the truck-frame upon its under side. The sliding or locking bar 3 has its end portion relatively reduced, if necessary, to enter radial sockets or notches formed by providing the truck-wheels upon the inner side each with a circular series or arrangement of projections or lugs 5 at the periphery, with their rims closing said sockets or notches at that point. Said sliding or looking bar has also at the points of conjunction between its reduced end portions and its body portion lugs or project-ions 6 to prevent it from jamming or binding upon the spokes of the wheels, as it were, as would be liable to otherwise occur. This bar or brake is adapted to be held automatically in engagement with the notches or sockets of the truck-wheels when itis desired to prevent the latter from turning on the axle by means of springs 7, coiled or helical, secured or connected to the truck-frame and said bar, respectively.

A cylindric bar or rod 8, carrying catches 9 at a suitable interval apart, has its ends let into sockets or eyes 8 on the castings or brackets 4: to turn therein, and connected to said rod near one end and the truck-frame is a spring 9 coiled. or helical, the function of which will presently appear. The rod or bar 8 has also a trip or projection 10 near its opposite end to provide for its convenient actuation by the foot or otherwise.

It will be seen that when the locking-bar 3 is withdrawn or disengaged from the radial or lateral notches or sockets of the truckwheels, which is effected by pressing downward upon said bar sufficiently to overcome the resistance of its springs, it (said bar) will be caused to pass into contact with the beveled u pper'portions of the catches 9 and below said catches. During such passage of said bar the catches yield and instantly or antomatically catch over the latter under the action of the spring applied to the rod carrying said catches, and thus hold said bar out of engagement with the truck-wheels. Of course in order to again effect engagement Of the locking-bar with the truck-Wheels it is only required that sufficient pressure be applied by the foot or otherwise to the catch-carrying rod through the trip or lug 1O thereof, said rod turning on its axes and permitting the catches to be disengaged from said bar, allow ing the latter to be automatically moved or slid into engagement with the wheel-notches under the action of its springs, as above intimated.

The locking of the truck-wheels, as is desirable when loading upon the truck what-- ever Weight or heavy body it may be required to move or transport thereon, aids to prevent the involuntary slipping or movement of the truck, though braced by the foot or body, or both, of the person using it, as well understood.

In the modification, as disclosed in Figs. 4 and 5, I may employ an arched locking-bar 11 to provide greater space for the application of the foot to the truck-wheel, axle as in loading the truck, and to this bar is suitably connected, as shown or otherwise, a guidebar 12, adapted to enter the contracted portions of the preferably skeleton brackets or castings 13. Springs 11L, suitably connected to the truck-frameorbracket and to said locking-bar, are employed for eifecting the automatic holding of said bar in engagement with the truck-wheels or their sockets or notches above referred to. To overcome the resistance of these springs in disengaging said bar from the truck-wheel notches or sockets, the foot is applied to said bar. In order to hold said bar out of such engagement, the guidingbar 12, connected. thereto, is caused to engage the downward-facin g shoulders 15 at the lower ends of the contracted portions of the slots of the brackets or castings 13, aided, if necessary, by the action of an additional spring (not shown) suitably connected to the truckframe or brackets and disposed or arranged to bear 'upon said guide-bar. Said lockingbar is provided with a trip or projection 17, which is more especially designed to provide for retracting or disengaging the guide-bar 12 from the shoulder 15, preferably by the application of the foot thereto, when it is desired to engage the locking bar with the wheels.

The cylindrical bar or red 8,with the catches 9, the castings or brackets 4, with eyes 8, and the parts for the manipulation of the same in general, as heretofore described, maybe used when desired in connection with the arched locking-bar 11. In other words, any desired part of one truck may be used in the makeup of any other truck, if preferred.

Having thus fully described myinvention, what I claim, and desire to secure by Letters Patent, is v 1. A truck of the character described, having its wheels each provided with a circular series. of notches or sockets near its periphery, guide-brackets, and a sliding bar having shoulders adapted to engage said guidebrackets, said bar also adapted to engage said notches or sockets, substantially as set forth.

2. A truck of the character described, having a sliding bar adapted to be automatically. held in looking engagement with its wheels, and a locking device for holding said bar disengaged from said wheels when not in use, substantially as specified.

3. A truck of the character described, having a sliding bar adapted to engage its wheels and a rocking bar or rod having catches adapted to engage said sliding bar, substantially as set forth.

4. A truck of the charaeterdescribed, having slotted brackets or castings, a springpressed sliding bar adapted to engage and lock the truck-wheels relatively to the axle,

a spring-pressed rocking bar or red having catches adapted to engage said sliding bar, substantially as set forth.

5. A truck of the character described, having slotted brackets or castings, a springpressed sliding bar adapted to engage and GEORGE M. \VILLIAMS.
